Taurid Complex Smoking Gun: Detection of Cometary Activity
Ignacio Ferrin, Vincenzo Orofino
Using the Secular Light Curve (SLC) formalism (Ferrín, 2010), we have catalogued 88 probable members of the Taurid Complex (TC). 51 of them have useful SLCs and 34 of these (67%) e…
Secular and Rotational Light Curves of 6478 Gault
I. Ferrin, C. Fornari, A. Acosta
We obtained 877 images of active asteroid 6478 Gault on 41 nights from January 10th to June 8th, 2019, using several telescopes. We created the phase, secular and rotational light…
1I/2017 U1 (Oumuamua) Might Be A Cometary Nucleus
Ignacio Ferrin, Jorge Zuluaga
In this work we find evidence that the object is of cometary origin.
A general method for assessing the origin of interstellar small bodies: the case of 1I/2017 U1 ('Oumuamua)
Jorge I. Zuluaga, Oscar Sanchez-Hernandez, Mario Sucerquia +1
With the advent of more and deeper sky surveys, the discovery of interstellar small objects entering into the Solar System has been finally possible. In October 19, 2017, using obs…
The Impending Demise of Comet C/2013 US10
Ignacio Ferrin
We have developed a 3-step criterion to decide if a comet coming from the Oort Cloud will disintegrate. If we apply this criterion to comet C/2013 US10 we find that the probability…
The Impending Demise of Comet C/2012 S1 ISON
Ignacio Ferrin
We present evidence to conclude that comet C/2012 S1 ISON is about to turn off or disintegrate.
The location of Asteroidal Belt Comets (ABCs), in a comets' evolutionary diagram: The Lazarus Comets
Ignacio Ferrin, Jorge Zuluaga, Pablo Cuartas
There is a group of newly recognized asteroids in the main belt that are exhibiting cometary characteristics. We will call them Asteroidal Belt Comets or ABCs. An analysis of their…
The orbit of the Chelyabinsk event impactor as reconstructed from amateur and public footage
Jorge I. Zuluaga, Ignacio Ferrin, Stefan Geens
A ballistic reconstruction of a meteoroid orbit can be made if enough information is available about its trajectory inside the atmosphere. A few methods have been devised in the pa…
A preliminary reconstruction of the orbit of the Chelyabinsk Meteoroid
Jorge I. Zuluaga, Ignacio Ferrin
In February 15 2013 a medium-sized meteoroid impacted the atmosphere in the region of Chelyabinsk, Russia. After its entrance to the atmosphere and after travel by several hun- dre…
Secular Light Curves of Comets C/2011 L4 Panstarrs and C/2012 S1 ISON Compared to 1P/Halley
Ignacio Ferrin
We used 1329 observations of comet C/2011 L4 Panstarrs and 1897 observations of C/2012 S1 ISON to create the Secular Light Curves (SLCs), and to compare them to comet 1P/Halley (31…
Modeling the Envelope of the Secular Light Curve of the Comete 1P/Halley
Eduardo Rondón, Ignacio Ferrín
We have been modeling the envelope of the secular light curve (Ferrín, 2010) of comet 1P/Halley. As the first step we have modeled the water production rate of the comet, for sever…
"Secular Light Curve of Comet 103P/Hartley 2, Target of the EPOXI Mission"
Ignacio Ferrin
In support of the EPOXI mission, we have compiled the secular light curve (SLC) of comet 103P/Hartley 2, the next target of EPOXI. a) Of the order of 30 photometric parameters are…
"Atlas of Secular Light Curves of Comets"
Ignacio Ferrin
In this work we have compiled 37,692 observations of 27 periodic and non-periodic comets to create the secular light curves (SLCs), using 2 plots per comet. The data has been reduc…
